Undo support for editor windows

I'm creating an editor window for my scriptable objects and I want to be able to undo the changes I make to it.

Currently I only call EditorUtility.SetDirty so that the changes get saved.
I tried also calling Undo.RecordObject, but that doesn't really do anything.

Is it possible to do using Unity's Undo system or will I need to handle Ctrl+Z myself?

 

I don't know what do you want to do exactly, but i found this documentation
https://docs.unity3d.com/ScriptReference/Undo.html

 

Yeah, as I said I already tried using Undo, but it turned out I was using it wrong.

I was calling it after making a change, instead of before doing it.
And I wasn't repainting the window when an undo was performed (I just assumed the repaint will happen), so I couldn't see it happen anyway.
